To Aall whom t mag/ concern." l

Be it known that.I,EDGAR;fRoUsE Sur- CLIFEE, a subject ofthe King of GrreatA Britain and Ireland, resid-ing at Leigh, Lancashire, England, have invented `certain new and useful Improvements Relating. to Presses for the ProductionofBricks', Briquettes, Blocks, and the like, of lwhich the following is a specification.

This invention relates to presses of the rotating mould table type for the production of bricks, `briquettes, blocks and the,

like from concrete, clay or'other materials or mixtures capable' of being moulded by pressure. Y

The invention especiallyA relates to the press of the construction and `operationdescribed in the specification of the' priorv Patent No. 7 44,430 November 17, 1903.

The invention has lamong its objects to improve theconstruction of the press and to adapt the press forl the development o f higher powers and 'speeds or for the production of bricks, briquettes or blocks of relatively large size, or bricks, briquettes or blocks compressed to a relatively high pressure.

The invention has also among its objects' to combine two presses for being fed with the material or mixture to be compressed from a single pan disposed between them.

According to the invention I provide .l

.to. Moreover the cam a may be provided means to balance the weight or part of the weight of the connected cross heads or the lower cross head.

According to the invention, moreover, means are providedv for pushing `the ejected brick, briquette or block from the top of the mould table after it has been raised from the mould. .l

VThe invention comprises the constructional features which are hereinafter described. The invention is illustrated by way of example in the accompanyingl drawings which represent a press of a construction 'generally resembling that described in the specification of the said prior patent, involving similar mechanism for operating mould table.

,y Figure l represents aside eleva-tion` of they disposed feeding pan. fFlgure 2 is a correspondingv side elevar tion partly in section; I g,

Figure 3 is -a further side elevation in which the mechanism is indicated for pushing-the brick,H briquette or block from the top ofthe mould 'table after `it has been raised from the mould. 'f j i n 4Figure 4 is a corresponding` fronteleva- FigureY a corresponding'plan. i i, y ,In carryingl the inventioninto effect-in its applicationy to a press of the kindl describedvin the specification 'of the said prior patent, I provide the plunger 1 by means of which thepcompressed bricks, briquettes or blocks are 4forced out ofthe moulds in the rotating mould table z', to' bel operable 'by means of alever 0l deriving movementl Vshortto bev usedy and avoids the necessity of -the usel of the bell crank lever employed in the construction ofthe prior patent referred as an'eccen'trically disposed boX cam having Y a circular cam groove which involves a practical advantage? in construction as well as in the operation of the machine. ,y y

It will'beunderstood that theshaft b upon which the operating cam a is mounted has imparted to it a movement at the same speed as that of the main shaft e through gearing from the first? motion shaft c. Thus ythe movementy is simultaneously imparted to the main shaft e and to the cam shaft b by which the ejecting plunger 1 is operated in the manner described. Y

As illustrated in the drawings and more particularly in Figures 4 and 5, two presses l the plunger, for ejecting the brick, or block, and for causing the rotation of theare provided having their mould tables respectively disposed on the right hand side and on the left hand side, so that the mould tables may be brought into juxtaposition and the respective horizontally disposed shafts brought into alignment, and thus a single first motion shaft c may be employe-d for both presses whereby a single drive may be applied from one end of the first motion shaft.

Such a construction permits of a single pan 0 being disposed between the respective presses and of mechanism being provided to impart movement to radial rakes or stirrers 01 within the pan by means deriving movement from the irst motion Vshaft c of the combined presses. These means may conveniently consist of la vertical spindle La) passing through a central vertical tubular boss 02 of the pan and upon the upper end of this spindle a boss 03 may be mounted to which the rakes or stirrers 01 may be connected. Movement is advantageously imparted to the vertical spindle p by bevel gear from a counter shaft g whose movement is effected by means of bevel gear from a spindle g1 driven by belt and pulleys from the first motion shaft c. The pan 0 is supported between the press frames by means of a supporting frame oL1 and is otherwise provided as is usual excepting that it is adapted to supply the material to be compressed to the two mould tables. Any other mechanism may be provided for imparting a rotary movement to the rakes or stirrers 01 of the feeding pan.

It will be understood that movement is imparted from the first motion shaft c to the respective presses through a toothed pinion l engaging the gear wheel 2 on the main shaft e and the toothed wheel 3 on the cam shaft vb. VMovement is imparted for the operation ofcompression by means such as described in the specification of the prior patent whereby no stress is imposed upon the mould table during the compressing operation so that thus only the dead weight of the connected cross heads L h1 rests upon the mould table noA matter what the degree of compression exercised. f

It will be understood that the movements involved in the compression within the mould, the eject'ment of thel brick, briquette -or block, and the partial rotation of the mould table'in the succession of operations of the press, are effected in the manner described in the specification of the prior patent aforesaid.

According to the invention moreover means are provid-eti to balance the weight or part of ythe weight of the connected 'crossheads t tl or of the lower' cross head it. Such means consist of a weighted lever f mounted beneath the main part of each of the press frames, they shorter arm f1 of which lever is pivotally connected to symmetrical arms g which are advantageously provided integral with the lower cross headh., the longer arm of the lever being provided with a weight f2 which conveniently upon bosses or base plates 251 t2 and theV centrally disposed base plate t1 may bev utilized for mounting the bevel gearV and spindle fg g1 through which movement is imparted to the verticalspindle p as aforesaid.

The respective weighted levers f are disposed in the plane of the cross heads It /tl and are advantageously carried from the main frame 1 of thev machine within brackets f3. i i

According to the invention, moreover, improved means are provided for pushing the ejected brick, briquette' or block from the top of the mould table z' after itv has been raised from the mould. These means comprise `a cam lr on thermaini shaft e and mechanism by which movement is imparted from the cam 7c to a vsliding pusher block m2. This sliding block m2 isy advantageously mounted upon a guide rod n or upon guides, and the rod n may be supported at one end from the press frame and at the .other by means of a rod nl, so that the block may move from the position indi-v cated in Figures l, 3 and'. 5 immediately above the table and adjacent that into which the ejected brick, briquette or block is raised,- into a position beyond the table and to the same radial line so that thus the pusher block m2 will force the ejected block radially outwards into a position on to a conveyor or table in front of the mould table i. Thus the'pusher block m2 does not slide upon the face of the rotating mould table c'.

The cam 7c from vwhich the movement ofthe pusher block m2 is derived is advantageously mounted upon the outer'end of the respectivemain shafts c from which movement is imparted by the cam lever 1 to a link m whose opposite end is connectedl to the short arm m1 mounted upon a horizontal spindle m3 disposed in position above the respective mould table vl and carried in suitable brackets from the frame. At the opposite end of this spindle m3 another longer arm m4 is mounted to eX- tend downwardly, at the lower end of which it is connected' by means of a link m5 with the sliding pusher block m2. It will be understood that the operating cam Ic and the ejecting mechanism are so provided that the movement of the pusher block synchronises with the operation of the ejecting plunger.
